770650 ÷ 12 
Our goal is to divide 770650 by 12.

On to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 12

Advancing to step 2:
77 divided by 12 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 72 from 77 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

Moving on to step 3:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 48 away from 50, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 12

Step 4:
If we divide 26 by 12, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 642.0
If we take 24 away from 26, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Advancing to step 5:
The number 12 fits into 25 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 6422.0
The remainder is 1 after subtracting 24 from 25.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

Step 6:
10 divided by 12 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 64220.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 64220.8
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 64220.83
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 64220.833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 64220.833, and the remainder is 0.0004.
